Cooper Discoverer SRX All-Season Radial Tire -245/60R18 105H Traction grooves maximize the expulsion of water away from the tread surface effectively reducing the potential of hyrodplane and increasing grip. Optimized 5-rib tread pattern evenly distributes the load across the tire's contact patch leading to improved treadwear, responsiveness and handling. Stabiledge TM helps stabilize the tread elements during driving conditions enhancing steering precision. 3-D micro-gauge dimple sipes maximize tread contact with the road surface to grip the road better. Winter edge feature creates a higher snow grip area in the tread to provide better traction.
